摘　　要：由于附加质量、浮力作用、重心位置的影响,飞艇的线化方程表达式较飞机复杂,国内外对飞艇稳定分析基本采用数值分析。本文通过推导与简化,给出飞艇侧、航向稳定性分析的简洁公式,阐明了影响侧航向稳定性的主要参数。最后通过示例计算,验证了分析方法的有效性。Airships are lighter-than-air aerial vehicles having unique properties that affect their dynamics including the effects of buoyant forces and the virtual mass and inertias.Additionally,the center of volume is far from the center of mass causing the system to act as a pendulum.The variety of operations that the airship must perform presents difficulties in creating a dynamic model of the ship.The main way of airship stability studying is numerical analysis at home and abroad.The pithy lateral stability formulas are given.And the main parameters affecting on lateral stability are also presented.At last,the analysis of validity is proved by an example.
